MACHINE FOR FASTENING CARD-CLOTHING TO FLATS.

SPECIFICATION forming part of Letters Patent No. 403,924, dated May 28, 1889.

Application filed October 25, 1888. Serial No. 289,084.- (No model.)

T0 all whom it may concern-.-

Be it known that I, WILHELM DECKER, of Mittweida, Kingdom of Saxony, Germany, have invented certain new and useful Improvements in Machinery for Fastening Card- Clothing to Flats of Oarding Engines, of which the following is a specification.

In my application for a United States Patent of October 19, 1888, Serial No. 288,893, I have specified new means for fasteningcard-olothing to the flats of carding-engines, said means consisting in a peculiarly-formed continuous row of clamps made of wire.

Now this present invention refers to improved machinery for fastening the card-clothing to flats by means of such continuous row of clamps. For this purpose my new and improved machinery is provided with two sets or pairs of pinchers or tongs, by means of which the piece of card-clothing is kept uniformly straight or tight in its entire length and width, while the fiat to be covered is pressed against the back of the clothing by means of eccentrics for such period as is required for making the holes in the clothing corresponding to those of the flat, for introducing the'wire (consisting of the continuous row of clamps) into such holes, and for temporarily connecting the clothing and the flat. The flat being thus attached to the clothing and the latter being held in the straight and tight position between the tongs or pinchers, these two partsviz., the flat and clothing-- are now turned over into such position that the binding-wires rest through their entire length upon angle-irons, which perform the dutyof anvils, so that the clamp ends protruding at the back of the flat may readily be bent or riveted down, thus uniting the fiat and card-clothing in a perfect manner.

Reference is to be'had to the accompanying drawings, forming part of this specification, in which-- t Figure 1 is an end view of the machine. Fig. 2 is a side View, partly in section; and Fig. 3 is a plan View thereof.

d is a fiat-carrier, provided with a suitable slot to admit the rib c of a flat, c, the horizontal parts of the flat resting upon the carrier (Z. The carrier is mounted within two fixed side guides, 6, supported in the frame of the machine, and may be moved in an upward direction by means of two cams, f, which are keyed upon a shaft, 9. The shaft 9 may be turned by a hand-wheel or otherwise. The shaft g may be supported in suitable hearings in the machine.

h is the lower fixed frame of the machine, to which, with the exception of the guides e and shaft g, with cams f, the entire upper part of the machine, hereinafter described, is hinged on the fulcrum i, in order to turn said upper part from the position shown in full lines into that shown in dotted lines in Fig. 1. This upper movable part of the machine consists, mainly, of two frames, h, at each end of the machine, each frame ,h carrying two supports, Z Z, which may be shifted in opposite directions by means of screw-spindles It, provided with right and left hand threads, that engage threads in the supports Z. Again, each frame h carries one support, n,between its two supports Z, which supports a may be shifted by means of the screw m in a direction at right angles to the movement of the supports Z.

The supports Z Z, on the same side of the machine and at opposite sides thereof, carry and are connected by the pair of pinchers or tongs 0 0, (see Fig. 3,) by which arrangement the two frames h at opposite ends of the machine are also connected. The supports n 'n carry each a pair of tongs or pinchers, p p. The two pairs of pinchers or tongs 0 0 take or grip the longest sides of the card-clothing I), while the two pairs of pinchers or tongs p p take or grip the ends of the card-clothing.

WVhen a flat provided with a row of holes near its longitudinal sides is to be provided with card-clothing, said fiat is laid down upon the carrier cZ, its rib 0 being passed into the recess of the flat-carrier d. The card-clothing b, with the wire teeth uppermost, is then laid upon the flat and its edges are gripped by the tongs o o and p p, whereupon the fiat is straightened and tightened by shifting the supports Z Z and n n, by means of the screw spindles 7a and m, lengthwise and crosswise of the machine. The flatc is then pressed by means of the eccentrics f toward the back or lower surface of the card-clothing Z). This latter while in the said position is now pierced with holes corresponding to those in the flat, and the continuous row of the wire clamps a is inserted into these holes of the card-clothing and of the fiat. I then connect the flat with the card-clothing at the ends, say by bending a few of the protruding clamp ends at each end ofthe fiat, so that when the eccentrics f are turned back, so as to cause the flat-carrier to recede, the flat will be carried 'by or hang underneath the tightly-held cardclothing. I then turn the upper framing, h, with all pinchers or tongs and with the cardclothing and flat around the fulcrum r, from the position shown in full lines in Fig. 1 into that shown in dotted lines in said figure, until the card-clothing with total length of wire on its two sides rests on the angle iron or rails q q, which,"for the subsequent bending and riveting down of the clamps protruding from the fiat, serve as anvils, the wires coming against the rails q. The clamps are then bent to hold the clothing to the flat by neans of a hammer or otherwise. After the bending or riveting has been completed tongs are opened and the fiat, with its attaehed card-clothing, is taken from the inachine. The fi'aniings hf, with their appen dix; are then returned into their normal position. ,1 ljhe rails q may b'e made movable to and from" each other, so asto make their position suitable for any width of flats and of cardclothing, if desired. r

raving now described my inven tion, what I laliiii 18-? 1. In a machine for attaching card-clothing toflafts, the suppor s; Z and tongs .0' 0, carried threbya ia means, substantially as de-, sea ed; formoving them laterally, combined with the supports 1%, n, having tongs p, and means, substantially as described, for m0ving said tongs, whereby said clothing may be stretched and held, and with a carrier for holding a flat against the stretched clothing, substantially as specified.

2. The flat-carrier 01, adapted to receive a fiat, and means, substantially as described, for raising and lowering said carrier, combined with means, substantially as described, for holding card clothing stretched above the flat to receive fastening for securing the clothing to the flat, as specified.

3. In a machine for securing card-clothing to flats, the supports 11 and tongs 0 0, carried thereby, means, substantially as described, for moving them laterally, and the supports n n and tongs p p, carried thereby, and means,-

substantially as described, for moving them, whereby clothing may be stretched and supported, combined with the carrier d,a dapted to hold a flat, and with means, substantially as described, for raising V and lowering said carrier to contact the clothing, substantially as described; I r 1 v I 4. The combination of the fixed frames h and pivoted frames h,- c'arried thereby, supports Z Z, tongs o 0', supports '7; n, ana ongs p p, and means, substantially as described, for moving said tongs to stretch clothing, and the anvils q q, to receive card clothing .carried by said tongs, all arranged siibstantia'lly as herein shown and described. 7

In testimony that I claim the foregoing as my invention I have signed my name iii pres ence of two subscribing witnesses.
